Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pair sinker used for knitting a knitted fabric in a circular knitting machine.

[0002]

2. Description of the Related Art Two types of sinkers, which can be controlled separately,
A method of knitting a pile knitted fabric by inserting it into a sinker groove of a book is described in, for example, Japanese Patent Publication No.
No. 264,341.

[0003]

FIG. 5A is a plan view of a sinker portion showing such a conventional example, and FIG.
(B) is 5b-5b sectional drawing in (a).

[0004] With the operation of the circular knitting machine, the cylinder containing the knitting needle rotates. On the other hand, sinker 6 cooperating with knitting needle
Numerals 1 and 71 are slidable in the radial direction along the sinker grooves 9 in the sinker dial 8 arranged in the horizontal direction. A load in a direction opposite to the rotation direction of the circular knitting machine (in the direction of the arrow) is applied to the sinker. When the bat 71b of the low bat sinker 71 receives a load, the bat bends in the direction of the arrow and presses the adjacent high bat sinker 61. Since the high bat sinker 61 is sandwiched between the low bat sinker 71 and the wall of the sinker groove 8, the movement becomes heavy, causing damage to the bat and heat generation.

The present invention has been made to solve this problem, and an object of the present invention is to prevent a bat from being damaged or generating heat by improving a pair sinker.

[0006]

A pair sinker according to the present invention comprises a separately controlled high bat sinker and a low bat sinker which are inserted into the same sinker groove during operation of the knitting machine. The rear tail is cut and shortened after the position corresponding to the bat of the low bat sinker, and in the low bat sinker, at least in the horizontal portion of the sinker corresponding to the bat position, the same as or higher than the high bat sinker It is characterized in that a slightly thicker spacer is provided. The present invention is also each sinker in such a pair sinker combination.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The sinker has a function of a horizontal portion which slides in a sinker groove, a bat which is controlled by a sinker cam, a sinker top located higher than the horizontal portion, and a shelf for forming the sinker top. A nose located above it, and a sinker throat between the nose and the sinker top. However, the present invention relates to an improvement in the vicinity of the butt portion, and the specific shape of other portions does not matter. The present invention can be applied to various types of pair sinkers.

[0008] The tail to be cut in the high bat sinker needs to be located at a position after the position corresponding to the bat of the low bat sinker. The specific cutting length is naturally determined in consideration of the sliding range of each sinker as a range that does not collide with the spacer of the low bat sinker during knitting.

The spacer set in the low bat sinker should cover at least the horizontal portion of the sinker corresponding to the bat position, and should have a thickness substantially the same as or slightly thicker than the high bat sinker. It is. As a setting method, for example, the spacer may be welded to the low bat sinker, or the spacer and the low bat sinker may be integrally formed from one metal plate.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a cylinder, on the outer periphery of which a needle groove 2 extending in the axial direction arranged in a circle is formed. Each needle groove 2 accommodates a knitting needle 3 slidable in the vertical direction.

A cam 5 for controlling or operating the knitting needle 3 is attached to a cam holder 4 facing the cylinder 1.

Sinkers 6 and 7 cooperating with knitting needle 3 during knitting
Is radially slidable along a sinker groove 9 in a horizontally disposed sinker dial 8. The sinkers 6 and 7 are controlled or operated by an inner sinker cam 11 and an outer sinker cam 12 mounted on a sinker cap 10.

Four to six yarn carrier ring supports 13 are arranged at equal intervals on the sinker cap 10, and a yarn carrier ring 14 is attached to the tip of the yarn carrier ring support 13. The yarn guiding device 1 is located below the yarn carrier ring 14.
5 is attached. The yarn guiding device 15 includes a holder 16 and a yarn carrier 17 for guiding the knitting yarn.
Having.

The sinker 6 to which the present invention is applied is a combination of two sinkers 6 and 7 called a pair sinker, and two sinkers are inserted into one sinker groove 9 two by two, and an inner sinker cam 11 and an outer sinker 6 are provided. Sinker cam 12
Are controlled individually.

The pair sinker shown in FIGS. 2 and 3 is disclosed by the present applicant in Japanese Patent Laid-Open No. 6-26, except for the features of the present invention.
No. 4341, where the sinker 6 is called a pile loop forming sinker and the sinker 7 is called a ground loop forming sinker. In this specification, focusing on the bat position, the sinker 6 will be referred to as a high bat sinker, and the sinker 7 will be referred to as a low bat sinker.

As shown in FIG. 2, the high bat sinker 6 includes a horizontal portion 6a that slides in a sinker groove, a bat 6b that is controlled by a sinker cam, a sinker top 6c higher than the horizontal portion, and a sinker top. A shelf 6d to be formed, a nose 6e located above, a guide edge 6f, a first sinker throat 6g between the nose and the sinker top, a second sinker throat 6h between the guide edge and the protrusion, most It has an upper edge 6i at a high position.

As shown in FIG. 3, the low bat sinker 7 includes a horizontal portion 7a that slides in a sinker groove, a bat 7b that is controlled by a sinker cam, a sinker top 7c higher than the horizontal portion, and a sinker top. A shelf 7d to be formed, a nose 7e located above, a vertical edge 7f, a sinker throat 7g between the nose and the sinker top, and a pile length determining edge 7 formed by the vertical edge.
h, the top edge 7i at the highest position.

A feature of the present invention is that, as described above, the tail 6j behind the bat 6b in the high bat sinker 6 is cut and shortened at least after the position corresponding to the bat 7b of the low bat sinker 7, and In the low bat sinker 7, a spacer 7j having substantially the same thickness as or slightly thicker than the high bat sinker 6 is provided at least in the sinker horizontal portion corresponding to the position of the bat 7b.

The tail 6j to be cut in the high bat sinker 6 must cover the bat position of the low bat sinker 7 without fail. In the illustrated embodiment, the cut is made several millimeters behind the bat 6b. However, the specific cutting length is naturally determined in consideration of the sliding range of each sinker, as it does not collide with the spacer 7j of the low bat sinker 7 during knitting.

The spacer 7j set in the low bat sinker 7 covers at least the horizontal portion of the sinker corresponding to the bat position, and is substantially the same as or slightly thicker than the high bat sinker 6. It is necessary. In the illustrated embodiment, the spacer is a thin plate that is approximately the same height as the horizontal portion of the sinker, is slightly thicker than the low bat sinker, and is fixed to the low bat sinker by welding. However, as a setting method, the spacer and the low bat sinker may be integrally formed from one metal plate.

[0022]

The operation and effect of the present invention will be described with reference to FIGS. 4 (a) and 4 (b). FIG. 4A is a plan view of a sinker portion of the present invention, and FIG.
4b is a sectional view.

In operation of the circular knitting machine, FIG.
Similarly, the load of the bat is applied in the direction of the arrow. But,
Unlike the prior art, the low bat sinker 7 of the present invention originally has an integral spacer 7j filling the space between the low bat sinker 7 and the wall of the sinker groove 8, and does not press the high bat sinker. Therefore, the high bat sinker exercises lightly without being affected by the low bat sinker.

Thus, the pair sinker of the present invention can prevent the bat from generating heat and being damaged when the circular knitting machine is operated.
